no thanks I am asking my teacher and dad to edit my ps for me. and @ maroc: bruv I am doing it all by myself aswell. some help will do no harm. so asked!

i have done my draft which is a page n a half long but i just wanted some good advise and more ideas.

hi, I am applying this year for aerospace engineering at university. i need some help with my personal statement. It would be great if anyone of you send a copy of good personal statements and ideas on what to write in it. Thank you

ya but which speed do i use?

wave speed = frequency * wavelength

the speed of sound in air is 330ms^-1 , speed of light is 3 x10^8 ms^-1... what's the frequency of radio waves of wavelength 100mm ?

thnx a lot!

A compass needle held horizontally is only afftected by the horizontal component of the magnetic flux. What do you think will happen to a compass needle at the magnetic north pole?

When the current in solenoid is turned off a steel core stays magnetized. The tiny atomic magnets remain lined up, even when the external field is removed. Why is that so?

If you reverse the direction of the current flow, will the direction of the magnetic field reverse?

thanks a lot!

1) Why do the electrodes in a linear accelerator get progressively longer? 2) What is a synchrotron? what is it used for? 3) How does a Geiger-Muller (GM) tube work? 4) How are particles detected in a hadron collider?

Speed = distance/time and current = charge/time. Explain how F=BIl is actually the same equation as F= Bqv but considered for many charges in a group? can someone please explain with working out please? thanks

Many real motors use electromagnets to create the magnetic field that causes their rotor to spin. Give one advantage and one disadvantage of building a motor which uses electromagnets rather than permanent magnets.

Having discovered up, down, strange, charm and bottom quarks, why did scientists undertake similar experiments using higher and higher energies?
